Be it known that I, ALFRED R. CUNNIUs, a citizen of the United States, residin Brooklyn, in the county of Kings and tote of New York, hove invented it new and uset' ful Sound-Augmenting Horn, of which the following is a. s ecification.

The principa obyect of the present 111V6I1 tron is to provide a horn, particularly useful in connection with phonogruphs, graphephones and similar sound reproducing instruments, which is comparatively simple in construction, and is composed of sections made of wood or other suitable material that fullness of tone that is so much desired.

A further object is to provide a horn that is very ornamental in appearance, and can be highly finished, the parts being com ere tively simple, and the different sections )eing held securely in place.

The prcfcrrcd embodiment of the inven' tion is i lustroted in the accompanying drew-- r ings, wherein Figure 1 is a side elevation of the horn,

showing the reducer in phi-cc thereon. Fig.

"detail longitudinal sectional view on the line 5 -5 of Fig. 2. Fig. 6 is a sectional view on the line 6-43 of Fig. 5. Fig. 7 is 21. detail View of one of the clip blanks. Fig. 8 is a. dc-

Similar reference numerals designate corresporulins pnrls in all the figures of the drmvings.

The smaller end of the horn comprises :1. mctsllictnporcd cull 11 provided at its larger ondwith sn :rnnulur enlargement 12, forming, an external unnuler shoulder. The body of the horn comprises a plurality of to cred sections 13, longitudinally curved and l at in cross section, said sections being preferably constructed of u plurality of layers of wood veneer glued together and. having the groin I crossed or dis )oscd 1n angular relat on, as

illustrated in Pig. 8. The inner and smaller ends of the sections are located in the enlnr cment 12. Tie stri s-14 are located bob tween the adjacent edges of the various sections and have their inner ends located in the enlargement 12, and secured thereto by rivets or other suitable fasteners 15. The opposite lon itudinal margins of the sections 13 are provi ed with continuous longitudinal dovetails 16 and the tie strips 14 have continuous dovetail grooves 17 in their opposite sides that are cngularly disposed and receive said sections. It will be noted that the channels forming the dovetails are cut solely in the outside ls ers and do not extend -com- 'plctely throng the some.

The outer end ed es of the sections 13 or inclosed by metallic binding strips 18. These strips are abutted at their ends against one another and against the outer ends of the tie strips 14, as will be evident by reference to Fig. 6. They are furthermore provided adjacent to their ends and in their outer sides With sockets 19. The various ubuttin ends are secured together by 'substentiefig U shaped cli s 20 that embrace the en s as shown in igs. 5 and 6, and are secured to the tie strips by rivets 21 or other suitable fasteners. These clips are provided at their outer ends with inwardly extending tongues 22 which tongues engage in the sockets 19. As a result, the clips lnterlock with the binding strips, preventlng their separation and said clips engaging over the ends of the binding str1ps,'serve to prevent their movement away from the tie strips and co'ver the oints between thepsrts.

For certain instruments of a. Well known type, the cuff 11 is slip ed into the/end of the rcproduccr tube, but or other types of machines, o reducin sleeve 23 is em loyed, the outer end of whi ill is enlarged and snugly re ceives the cull 11, being ubuttedngainst the external shoulder thereof and dctochably fastened thereto by a screw 24, which screw may also be employed forsecuring the cuff 11 in place on the instrument, when the sleeve is not in use. This sleeve is rovided at its inner end with a. contracts tubular nipple 25 on which the end of the sound conveyor tube may be placed as will be evident sold nipple forming an annular internal Shllllflflt that shuts against the end of the on This structure as will be evident is comparatively simple, being an ular in cross section, as shown in Fig. 4 our the sections are cfl'cctivcl y hold together so that there is little chance of their becomingseparated.

be clamped by the tie strips.

detachable reducer shown, said horn can be T readily used in eoaction with both of the two general types oi sound reproducing machines now known.

From the foregoing, it is thought that the construction, operation and many advan tages ol' the herein described invention will be apparent to those Hhllltd in the art, with out turther description, and it will be understood that various changes in the size, shape,

proportion and minor det ails of construct ion,

may be resorted to without departing from the spirit or sacrificing any of the advantages ot' the invention. For instance, in. Fig. 3 there is. illustrated a modified form ol' tie strip, desigm'lted l4, this tiestrip being constructed of sheet metal bent to produce the opposite sides and longitudinal dovetail grooves 17- in its opposite edges.

nnother embodiment of this invention is shown in Fig. 10. In this form of construction the t-ie stl'ip 14" is constructed oi two pieces of sheet metal that are doubled and substantially U-shaped in cross section,

.i'orming the opposite longitudinally disposed dovetail 17. 'lhe abutting rear lac-es oi the sections are soldered or otherwise secured together. i

Having thus l'ullydescribed my invention, what 1 claim as new, and desire to secure by Letters Patent, is:-

1. A sound augmenting horn, comprising a ta ered cutl' having an annular external shou der between its ends, a. horn body sceured to the cuil a tapered reducing sleeve that detachably lits upon the cull and has one end abutting against the shoulder, said sleeve having an internal shoulder that abuts against the end of the cuil, and means for detz'ic-hably securing the sleeve to the cull.

2. A sound augmenting horn angular in cross section and comprising tapered sections, each section being longitudinally curved and transversely Hat and each having its opposite side margins formed into eontinuous longitudinal dovetails, and tie strips 10 *ated between the sections, each st rip having longitudinal dovetailed sockets in its opposite sides that, are angnlarly disposed with relation to eaclfother and receive the adjacent dovetailmliinargins of the adjacent sections.

3. A sound augmenting horn, comprising neeting the binding elements and having portions interlocked therewith.

4. A sound augmenting horn, comprising sections, binding elements enga ing the ends of the sections, and holding e ements connet-ting the binding elements, one set of ele- Inasmuch as the dovetail forming channels are located solely in the outside layers, said layers will By having the f ments being provided with sockets, theothe-r having tongues that engage in the sockets.

5. A sound augmenting horn, comprising sections, binding elements engaging the ends of the sections and having sockets in their end portions, and holding clips connecting the end portions of the binding elements and having tongues that engage in the sockets.

6. A sound augmenting horn, comprising sections, tie strips connecting the longitudinal margins ol' the sections,binding strips engaging the ends of the sections, and clips secured to the strips and having portions interloeked with the end portionsol' the binding strips. i

7. A sound augmenting horn, comprising sections, lie strips located bet-ween and embracing the longitudinal margins of the sections, binding strips engaging the ends of the sections and having sockets in their end porlions, and clips secured to the outer ends of the tie strips, and having spaced inwardly extending tongues that engage in the sockets ol' the binding strips.

In testimony, that. I claim the 'lore oing as my own, 1 have hereto allitied my signature in the presence. of two witnesses.
